The Night Vision Mount Adapter from Bering Optics enables you to attach your night vision monocular to a helmet or a head gear for hands-free operation. On one end this adapter connects to your NVD' mounting point. On the other, it attaches to the required Bering Optics BE80127 Universal Arm via a dovetail interface. This adapter features a wide knurled knob for clamping the mounting point, a quick-release lever for detaching your NVD from the headgear, and a button for switching your night vision monocular from one eye to another.
